Claims (1)
Patent-Anspruch:Patent claim:Hydraulische Hebevorrichtung, dadurch gekennzeichnet, daß zwei nach entgegengesetzten Richtungen wirkende Lastkolben
• (1,4) übereinander angeordnet sind, zwischen denen die Pumpen (9, 12) und der
sie umgebende Aufnahmebehälter (7) für die Druckflüssigkeit eingebaut sind.Hydraulic lifting device, characterized in that two load pistons acting in opposite directions
• (1,4) are arranged one above the other, between which the pumps (9, 12) and the
they are built in surrounding receptacles (7) for the hydraulic fluid.
Clamping device e.g. zero-point clamping device has clamping slide side coupling portion arranged in housing so that transfer of lateral forces to receiving portion is supported in region perpendicular to movement direction of actuator
